I was playing the online Battle for Moscow (again). The rules allow the Soviets a railroad movement phase before the combat phase and the resulting normal movement phase. Early in the game, Soviet forces often use the rail movement to escape from the Germans. Later, sometimes they use rail movement to exploit gaps in the German lines in front of Moscow for counter attacks.
It struck me that one could have a fine scenario for either of these cases if you had a armored train model. I already have N scale tracks (I think), used for ACW and FPW games as places for infantry to take cover. This presumes that the Germans aren't across the tracks but can bring them under fire. If they were across the tracks they'd just blow them up or pry up the rails.
Any ideas for where to get models? I don't care if they actually move, not being a model RR guy. The rails just function as terrain.
